Again the work now is mostly fixing bugs but we have to re-work some areas, although none of it is major. If it were to be used in casinos now, the processes wouldn't be streamlined or as practical as they should be.
One of the new programmers (two brothers) has started coding. The other just requires a bit more understanding before starting to code his part.
I've made an arrangement with the previous programmer to be paid upon completion in 7 days. In other words if he finishes in time, he gets paid a significantly larger amount. This is not the first time we've made such arrangements. The result is usually good progress is made, but not completion. I expect the same in this case, so the likely result is the additional work done can be passed to the new programmers who are much more reliable.
Depending on the progress each team has made, there may be code-sharing or the work will remain independent.
Christmas and New Years shouldn't delay things too much, perhaps add an extra 4-5 days. This nightmare of a development is really almost over, maybe before Christmas. If it isn't, it wont be long after regardless of who completes it.
